HARRY A. WILLS, OF KEESEVILLE, NEW YORK, ASSIGNOR TO A. W. KINGSLAND, OF SAME PLACE.

MACHINE FOR MAKING HORSESHOES.

Specification of Letters Patent No. 29,042, dated July 3, 1860.

To all whom it may concern:

Be it known that I, HARRY A. IVILLs, of Keeseville, in the county of Essex and State .of New York, has invented certain new and useful Improvements in Machines for Making Horseshoes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which Figure 1 represents a front elevation of my invention. Fig. 2 is a transverse vertical section of ditto, the line a}, 00, Fig. 1, indicating the plane of section.

Similar letters of reference in both views indicate corresponding parts.

This invention consists in arranging the shaping die or mold of a cylinder machine with a movable front, which when thrown forward bends the iron to the required shape and holds it in the proper position until the swaging die grips it, and then being thrown back allows the iron to spread; and it consists also in the employment of a crank shaft which is subjected to the action of a spring and the bent end of which sweeps over a stationary die which is rigidly attached to the side of the frame which forms the bearings for the cylinders so thatat the proper intervals said front is drawn in and the iron set free.

To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation with reference to the drawings.

A, A represent the frame which forms the bearings for the cylinders B, B. This frame is made of cast-iron or of any other suitable material of suflicient strength to sustain the strain necessary for the operation of making horse shoes.

The lower cylinder B, is provided with the female die O, and a cam a, projecting from its surface serves to operate the cutter b, which is attached to the curved bar D, and which in combination with the stationary cutter 0, cuts off the blanks to the required length in a similar manner to the machine for which a patent was granted to me on the 2nd of March 1858.

The swaging die E, is secured to the surface of the upper cylinder B, and two curved grooves d, cl, on the sides of this die and in the surface of the cylinder B, form the guides for the vibrating arms 6, e, which hold the blank after the same has been cut, and bend it around the mold or shaping die F. In bending the blank around the mold it is necessary to allow the same a certain amount of play so that it can spread under the action of the swaging die, and if the iron is bent through the action of the front of said mold itself, it will lay close up to the mold or at least to the front of the mold and no chance is left to the same to spread.

In order to avoid this difficulty I have made the front 7", of my mold movable, and I have arranged it so that the same recedes and gives to the iron room to spread under the action of the swaging die E.

The front 7, is attached to an arbor 9, that passes through the interior of the cylinder 13. One end of this shaft extends beyond the side of said cylinder, and a crank it, is attached to it which by sweeping over a sta tionary cam 2', on the side of the frame A, keeps the front f, up. A spring 7', attached to the front f, and operating in the interior of the cylinder B, has a tendency to throw the front back as soon as the crank 72,, is re leased from the cam 2'. This cam is furnished with a shoulder 76, in passing which the crank it, is suddenly released, allowing the front f, to recede through the action of the spring j, and the shoulder 7?, is in such a position that said front is thrown back just before the action of the swaging die on the blank begins. By these means I have accomplished in a simple and effective manner what otherwise requires a complicated machinery and at the same time the front f, can be made to project far enough so as to afford a good hold on the blanks without interfering with the action of the swaging die.

After the horse shoes have been completely formed by the action of the two cylinders B, B, they are taken up by the clearer H, from whence they are removed and put away in a boX or in any convenient receptacle.

I do not claim broadly the employment of the movable front of the shaping die of a horse shoe machine; but

Having thus fully described my invention,
